Export assignment umuldw

• umuldw(out: ArrayLike<number>, a: number, b: number): ArrayLike<number>
• umuldw(a: number, b: number): ArrayLike<number>

• Performs multiplication of two unsigned 32-bit integers and returns an array of two unsigned 32-bit integers which represents the unsigned 64-bit integer product.

  Notes

  • When computing the product of 32-bit integer values in double-precision floating-point format (the default JavaScript numeric data type), computing the double word product is necessary in order to avoid exceeding the maximum safe double-precision floating-point integer value.

  Parameters

  • out: ArrayLike<number>

    output array

  • a: number

    integer

  • b: number

    integer

  Returns ArrayLike < number >

  double word product (in big endian order; i.e., the first element corresponds to the most significant bits and the second element to the least significant bits)

  Example

  var v = umuldw( 0xAAAAAAAA, 0x55555555 );
  // returns [ 954437176, 1908874354 ]
